Dodecad Oracle (K12a edition)

You can refer to the original Dodecad Oracle for detailed usage instructions.

(The only difference in the use of the program is that the number of populations is 204, so make sure to use this if you plan to remove any reference populations, as mentioned in the instructions)

In short:

you first load the file DodecadOracleK12a.RData in R. You can do this by double-clicking on this file in Windows, or using the File->Load Workspace menu. In Linux, you can use the "load" command, e.g., load('/home/ubuntu/Desktop/DodecadOracleK12a.RData')

Not sure why I'm getting Mixed Germanic and Dutch before CEU and the British populations in that I'm a Tennessean with roughly 3/4ths British Isle's ancestry, the remaining quarter being a mix of German and Iberian.

Brits and Utahns do make the list in some measure so the results seem believable.

I found out why my results were a bit funky, I did not catch that you had an individual results tab with my ID in it (DOD152) so I had tried to run the DIY version and came out with slightly different results than what was in the spreadsheet so I probably did something wrong.

With the spreadsheet results my Oracle results seem more in line with my ancestry.

You stated that "(t)he numbers to the right of each result represent the 'goodness' of the match; the lower, the better". How high do these numbers of "goodness" go and what is a lower number that is best to have?

The number can be as low as zero if your admixture proportions are exactly equal to the average proportions of a population or a 2-way mix. You can compare your results with the population averages to see which components make up most of the difference.

Useful software
